Answer:
$17,835.90
Explanation:
Currently Hodgkiss is operating at 92% of its fixed asset capacity, so they have an spare 8% to grow without adding any more fixed assets: ($780,000 / 92) x 100 = $847,826.09.
So they need to add fix assets in to increase its production by $32,173.91 (= $880,000 - $847,826.09).
Every dollar spent in fixed assets generates at full capacity $1.8039 in production output (= $847,826 / $470,000).
If they want to increase production by $32,174, they will need to spend $17,835.90 in fixed assets.
